Rated 5 out of 5 by from Excellent Excellent. Well made. Good fit. Hood could extend further at the sides to fully protect the face and could possibly have a peak at the front of the hood

Rated 5 out of 5 by from Great fit for 6 month old Fits perfect on my 6 month old! Love the hood on it! We call it her Elvis outfit because the legs flare out when unbuttoned.. haha!!... she looks so cute in it but it’s also great at keeping her protected from the sun... wish there were different prints available tho!!

Rated 5 out of 5 by from Great Suit I love this suit for my little one. She is large for her age (7 months wearing 9-12 months) and this suit still fits. I love that is it full coverage so that I can put less sunscreen on my baby.

Rated 5 out of 5 by from Absolutely love it! I bought this for my daughter a couple months ago for her to wear on our boat with no shade. We finally used it today but in the pool. WOW! I’m very impressed and happy with it. The material is amazing! We were able to keep her under shade in her float and know she wasn’t going to get burnt. Her arms, legs, and head all are covered—which is nice considering she can’t wear sunscreen yet. I was actually able to keep her out in the water longer! And let’s not forget how darn cute it is on! As far as sizing, she is now 4 months old and fits in the 6 month one. She’s ahead growth wise, so hopefully we can wear it another month or so. I will definitely be buying one of these in a larger size for when she outgrows this one!

Rated 5 out of 5 by from Perfect for Beach or Pool Bought this for MN summer pool season for my granddaughter just before 2 weeks in Jamaica. She was at the beach each day - all day - and was totally protected. What a lifesaver.

Rated 2 out of 5 by from Nice sun protection but a few disappointments The suit overall is well made and super cute. It's easy to get on and off and I love the hood. Two things disappointed me however. The snaps under the legs are constantly popping open. Everytime I switch how I'm holding my 6 month old, they pop. Also, I didn't think of this until we were actually in the pool, but the blue color blends right in with the pool. I think Coolibar should avoid this aqua blue color for all their suits. If a child were to struggle in the water(or drown), you wouldn't even notice it because they blend right in with the water. I would suggest an orange or red suit vs. blue.

Rated 5 out of 5 by from Amazing product! I bought two one piece swimsuit to our vacation in Punta Cana. The long sleeves and full legs plus the hoodie are perfect and kept my baby fully protected . Also, the buttons on the legs are so practical for a diaper change! It was 31C and super sunny everyday and my 4 months old baby girl was super comfortable in her swimsuit. No tan, no sun burn and no heat allergies. The product has a very good quality and finishing , and the moms around we’re asking where I got it from . I love the product and will buy again for our next vacation. :)
